Summary MESS-specific 06415: oric1, orica, telstrat, prav8d, prav8dd: Microdisc floppy images are not loaded at all.
Description When trying to load any disk images with any version of MESS it always gives the error "No operating system on disk".
Tested for example with that works normally with the Oricutron emulator, supplied in the archive.
Any other disk images give same result. Selecting the microdisk and the floppy image normally from the interface didn't work as well, even if message that loading of the disk was successful. Even converting the images to other format didn't solve the problem.
Steps To Reproduce mess64.exe orica -ext microdisc -flop A0XB.dsk
Additional Information Tested with older versions with same result.

Tested with numerous disk images. The 188KB ones hung; the larger ones crashed MAME; not one worked.

As far as I know, Telstrat has never worked properly. The other systems in the driver don't support floppies.
